thanks for the fix. 
Installed the proposed version. 

# apt-cache policy unbound
unbound:
  Installed: 1.13.1-1ubuntu5.12
  Candidate: 1.13.1-1ubuntu5.12

I am able to resolve the MSFT hostname that has more than 8 CNAME chains now. 
Would like to run more tests, but it is looking good so far. Hope that MSFT 
does not provide CNAME chains larger than 11 now. :)
